Yes, I know,
Zombie Thread Alert.

However, I had someone ask me about a W-series dread, & this is like the ONLY authoritative thread I could find on the subject, so I figured it deserves a little resurrecting.
Specifically, let me transcribe the ad copy to get rid of the little squinty letters. IMNSHO, they really don't stand out as particularly thrilling instruments, but that's partly the fault of the copywriter, who really didn't have much to work with.

Therefore, I am grafting on the "missing" page for the W-500 & W-600.
The W-280 Dreadnought
Handcrafted of select fine grain woods, the W-280 Dreadnought boasts a solid spruce top and hand-shaped and fitted spruce bracing to enhance the tone qualities of this fine instrument.

One question: does anyone know when these Washburns first sold? The blurb for the 260 suggests it was actually before 1974.
